A problem when exporting Arabic PDFs on Docker

[Mohamed]

Hi,

Arabic reports work well on Windows, but when the app is published to Docker, the report viewer shows the correct report, but when printing or exporting PDF, the report is drawn from left to right with incorrect format and layout.

Here is an example of a Docker PDF

, but this is the correct report on the Report Viewer

Hi Mohamed,

Generally, printing from the Html5-based Report Viewer involves rendering the report in PDF. For that reason, I assume that the issue occurs only when rendering in PDF on Docker. Do you mean Docker with Linux?

If so, note that the GDI+ implementations for Windows and Linux differ, which may result in differences in the rendering.

In PDF rendering the fonts get embedded in the document and have to be available on the service. If not, the Reporting engine will substitute them with a default one, which may result in unexpected output.

Are the fonts you use in the Report available in Docker? Do you use private fonts?

Which fonts do you use?

Did you check the embedded fonts in the PDF generated in Docker? Were they the ones you expected to see?

I tested locally to export a Report localized in Arabic to PDF from Windows and Linux Docker. The final documents differed as in Docker the font was substituted. However, in both documents, the text was rendered from right to left as expected.

Here are some resources you may find useful:

• Characters do not appear correctly in PDF files
• Deploying on Linux
• PDF Rendering Font Requirements
